Advances in Biosensors Technology for Detection and Characterization of Extracellular Vesicles

open access: yesSensors, 2021
Exosomes are extracellular vehicles (EVs) that encapsulate genomic and proteomic material from the cell of origin that can be used as biomarkers for non-invasive disease diagnostics in point of care settings.

Microneedles in Advanced Microfluidic Systems: A Systematic Review throughout Lab and Organ-on-a-Chip Applications

open access: yesPharmaceutics, 2023
Microneedles (MNs) have been widely used in biomedical applications for drug delivery and biomarker detection purposes. Furthermore, MNs can also be used as a stand-alone tool to be combined with microfluidic devices. For that purpose, lab- or organ-on-a-

Ruthenium Oxide Nanorods as Potentiometric pH Sensor for Organs-On-Chip Purposes

open access: yesSensors, 2018
A ruthenium oxide (RuOx) sensor for potentiometric pH sensing is currently being developed for organs-on-chip purposes. The sensor was fabricated from a Ru(OH)3 precursor, resulting in RuOx nanorods after heating.

Lab-on-a-Chip method uncertanties in determination of high-molecular-weight glutenin subunits [PDF]

open access: yesChemical Industry and Chemical Engineering Quarterly, 2013
Polymeric wheat endosperm proteins, especially the high-molecular-weight glutenin subunits (HMW-GS), are probably the most interesting protein fraction giving the essential information about bread-making quality of wheat flour.

Ruthenium Oxide pH Sensing for Organs-On-Chip Studies

open access: yesProceedings, 2018
A ruthenium oxide (RuOx) electrode is being developed as potentiometric pH sensor for organs-on-chip applications. Open-circuit potential (OCP) of the RuOx electrode showed a response of −58.05 mV/pH, with no cross-sensitivity to potentially ...

Online monitoring of biofouling using coaxial stub resonator technique

open access: yesSensing and Bio-Sensing Research, 2015
Here we demonstrate the proof-of-principle that a coaxial stub resonator can be used to detect early stages of biofilm formation. After promising field tests using a stub resonator with a stainless steel inner conductor as sensitive element, the ...
